i want to start a preservation of the original mono mix the great escape, because this mix not included on the blu-ray. for this project i have the old u.s. dvd which contains the mono mix in dolby audio. but a full preservation would could only be achieved by using the uncompressed audio, which can be found on the criterion laserdisc.

so anyone can help me getting the laserdisc audio, this would be very much appreciated.

thanks in advance
